Ubuntu :: Injecting Commands Into Different Terminal Windows
Jul 30, 2011
I have a terminal window running a game server in Ubuntu 11.04. no problems at all.I also have a backup script, which simply uses cp to save copies of the level files. this is run as a scheduled task every 20 minutes.What i'm trying to do, is as part of the backup script issue a command in the game server terminal window (forcing a save of the level) before the cp command takes place.
Two days of googling and i have failed to find a solution, anyone have any ideas?one thing i was also trying to figure out is how to identify the game server terminal window, maybe by changing the 'Terminal' text at the top. is this possible?

I have UDP packets generated on Machine A that are addressed to Machine B (unicast) that I capture with PCAP. After transporting this raw data to Machine B (via RF modem) I'm trying to reinject the original UDP on Machine B through a tap0 interface. The capture and transport are all working fine. BUT once on the destination machine, the reinjected ethernet packets are NOT being received by a local UDP server. this is my socket creation :
Code:
outputSocket = socket(AF_PACKET, SOCK_RAW, htons(ETH_P_ALL));
struct ifreq s_ifr;
strcpy(s_ifr.ifr_name, "tap0");
"data" is an unsigned char array that contains the original packet data received from pcap, which includes the ethernet header, ip header, udp header, and payload data. after the call to write() completes, Wireshark on Machine B sees a correctly formatted (checksums and all) UDP packet when listening to tap0 - ie. no lines highlighted in red. *BUT* - a UDP server i have running on Machine B never receives the reinjected UDP datagram. (I have verified that this server works, by using a simple local udp generator app.) is there something wrong with how I'm creating the socket and/or writing the data back out to the tap0?

if you do the command conky in terminal, it starts conky ofcourse, but it also shows output to that terminal so you can't do any other commands to that terminal, Is their an option like you can do with the '&' sign in other cases? If you do the '&' sign with conky it still gives output, also the conky -d command gives output...

I am in the process of coverting some video files to motion jpeg (Wii) files with ffmpeg (great program by the way). I have been successful and so the majority of my work is over. My question is simple (I think) but complex to me so... here it goes. Is there a way on one command line to "batch" convert 8 or 9 files together instead of one by one. I just don't know what to put on the command line. I took one UNIX class a long time ago and the terms pipe and such come to mind... but I forget. Any takers? That was I can write what I want the computer to do in the morning and just come back after work and voila...

I was following a guide to stop Ubuntu from always asking the root password. And apparently i messed something up in vsudo edit or something like that i was in... So now when i put in a sudo command i get this...
Quote:
>>> /etc/sudoers: syntax error near line 18 <<<
sudo: parse error in /etc/sudoers near line 18
sudo: no valid sudoers sources found, quitting
so i cant even get back to undo what i edited.

I couldn't really find a general Ubuntu discussion area. So I typed ipconfig and of course it said no such command blah blah blah. What I found interesting was that it provided a list of other commands I may have meant to use, ie. ifconfig. So what's the algorithm used to determine the commands? Is it SOUNDEX or something else?

I upgraded to 11.04 today and wanted to reconfigure so that I could have the desktop cube again. Once I started trying to switch my settings for the cube configuration compiz asked whether I wanted to turn off various features and apparently among them was the control bar on the side and top of the screen. Now I log in to Ubuntu and I get my workspace and that's it. No control bars, just the workspace. I need to know a few things:
1) Has anyone else had this problem?
2) How do I get into the terminal from keyboard commands?
3) What terminal commands do I need to bring back at least the main toolbar so I can access programs.

I was wondering if there was a way to show all current actions I am doing in a terminal window? For example if I left a terminal window open on one of my desktops, could I make it display everything I am doing so that when I receive some general error in a program, I could jump over and get some more details. I could also use it to see what commands are actually run when I do certain things.

I mean, obviously I can just type them out and italicize them or something equally boring, but what I'd like to do is make the code look like it does on these forums.Code:sudo apt-get install html-knowledgeI've been Googling like a mad man (not a euphemism) for the better part of an hour and can't turn up any pertinent results. I thought maybe somebody here could point me in the right direction. I'm tired of my blog posts looking ugly and disorganized when I start typing commands.

We have created a stripped own version of Ubuntu 10.04 LTS, and removed the screen saver and power management options from the desktop as we have turned off the menu. The reason for this is security as we do not want users having any other options then what shows on the desktop. What is the sudo command to get back to this or do I need to under the administrator profile Create a Launcher icon?

While trying to make a Winmodem work, I've installed drivers, done magic incantations in Terminal, etc., without keeping complete records of what I did. Is there a "clean" routine or something that will remove unused drivers, or do a system rollback, or some other way to clean up the mess?

With xterm, I can do the following, and the scripts are executed sequentially in a single xterm: xterm -e 'script1.sh;script2.sh' But with gnome-terminal, when I do: gnome-terminal -e script1.sh;script2.sh It runs them in parallel in 2 different terminals. I've tried a few combinations of ", and ', around the scrips, but no difference.

I was trying to navigate by terminal and tried to change directories by typing- cd ./documents and terminal states no such directory. I can only navigate folders that I created with mkdir. Do I need to set permissions somewhere? Yes documents does exist in my home folder and I tried to open others with no luck.

I had automated some tedious commands in the terminal by writing them in a text file and placing an icon on the panel. By clicking the icon the commands ran in the terminal automatically. I cant for the life of me remember the icon command I used to get this to work.

The other day I was practicing some of the famous Awk One-liners and noticed something interesting in the bash shell on ubuntu 9.04. Some specific awk commands would execute correctly but when I tried to use an up arrow to re-run the command that particular command was not present in my history. Is this an issue specific to me? specific to awk? Completely random?
